Because this Gauss Rifle disagrees with you. It can accelerate 10g Depleted Uranium w/ Tungsten NanoCarbide reinforcement and a nanogram of Quarkium at its core at .6c, and I can throw these downrange at 900 RPM.

The impact of a single round is akin to that of a 16" gun that they mount on BATTLESHIPS.

Any breach of the containment field around the Pure Quarkium inside the bomb will kill us all, remember that.

But it doesn't have to come to that, put down the Element of Chaos, and I will defuse the bomb. If you do not comply in the next 10 seconds, the bomb WILL detonate, I will die, so will you and everything in a 1 AU radius.
